SolarEdge is developing advanced power-harvesting solutions for photovoltaic arrays. It will lower the average cost per watt in any typical photovoltaic installation via increased wattage and lower costs, provide for easier and cheaper installation, and help make Photovoltaic (PV) installations relevant in more sites. SolarEdge was the first to break into the global market with a unique distributed power harvesting and monitoring system which they say will increase the efficiency of photovoltaic solar arrays. Generally the electrical output from solar rays (usually about 15 solar panels lined up in a row) are controlled by a single device which decides how much voltage and current to use at any given time. Since the panels’ outputs are linked, if one panel is affected by an outside factor like share or malfunction, the entire efficiency of the array is reduced. SolarEdge has pioneered a product which offers individual command and control of each panel. A specially developed power box with specifically designed microchips is attached to each panel which provides constant information which enables individual calibration. In addition to the power boxes, the company has developed more efficient, smaller and lighter inverters, which convert the Direct Current (DC) from the panels to the current used in households, Alternating Current (AC). In addition, the power boxes have been designed to withstand high temperatures in a solar field for 20 years. The individual panel monitoring function will also help improve efficiency and security. Until now, if a drop in efficiency was noted, technicians had to go row by row to check if a panel had been damaged, which can be time consuming with arrays of thousands of panels.
